In the late Tang Dynasty, the world fell into chaos, with warlords dividing territories and heroes rising everywhere. It is said that before the rebel army of Huang Chao captured Chang'an, the mysterious organization within the government—the "Buliangren"—carried out one final mission and then vanished without a trace. Almost simultaneously, the national treasury treasure, which the rebels searched all over Chang'an for but never found, also disappeared. Since then, a rumor has spread throughout the martial world: the legendary Dragon Spring Sword holds a monumental secret. One day, a mysterious orphan named Li Xingyun was fortuitously saved by the hermit Yang Shuzi and became his disciple to learn martial arts. Years later, Li Xingyun and his junior sister Lu Linxuan descended the mountain to gain experience. Along the way, they befriended Ji Ruxue and Zhang Zifan and later accidentally obtained the legendary Dragon Spring Sword. As a result, Li Xingyun and the Dragon Spring Sword attracted the covetous eyes of various factions, including the Xuanming Sect, Tongwen Hall, Huanyin Workshop, and the Celestial Master's Mansion. These groups schemed in various ways—some resorting to trickery and force, others issuing warrants and pursuing relentlessly, employing every possible method. Even the long-lost "Buliangren" showed signs of reemerging in the martial world. Li Xingyun, this youth of mysterious origins, thus navigated the perilous martial world alongside his friends, struggling to find a path to survival.
